Typically, hemipelagic sediment is transported to the continental slope in suspension from river mouths but can be transported by the wind. [3] The rate of deposition of hemipelagic sediment is higher than pelagic sediment but still quite slow. [9] Ordinarily hemipelagic sediments accumulate too rapidly to react chemically with seawater.
Obduction zones occurs when the continental plate is pushed under the oceanic plate, but this is unusual as the relative densities of the tectonic plates favours subduction of the oceanic plate. This causes the oceanic plate to buckle and usually results in a new mid-ocean ridge forming and turning the obduction into subduction.

Marine sediment, or ocean sediment, or seafloor sediment, are deposits of insoluble particles that have accumulated on the seafloor.These particles either have their origins in soil and rocks and have been transported from the land to the sea, mainly by rivers but also by dust carried by wind and by the flow of glaciers into the sea, or they are biogenic deposits from marine organisms or from ...
An abundance zone, or acme zone, is a biozone that is defined by the range in which the abundance of a particular taxon is highest. [6] Because an abundance zone requires a statistically high proportion of a particular taxon, the only way to define them is to trace the abundance of the taxon through time.
Academician Ridge is an underwater, structural high separating two of Lake Baikal's three basins, the Central and North basins Situated in the central part of the Baikal Rift, it serves as an "accommodation zone", transferring "motion between faults of similar displacement but different orientation" (Hutchinson et al., 1992).
